Department of Radioelectronics

Synopsis:

The course provides fundamentals of digital communications theory: modulation, classical coding, channel models, and basic principles of decoding. The exposition is systematically built along the theoretical lines which allow to reveal all inner connections and principles. This allows students to develop the knowledge and use it in an active way in a design and construction of the communication systems. The course provides a necessary fundamental background for subsequent more advanced communications theory courses.

Requirements:

None

Syllabus of lectures:

1. Digital modulation and coding, basic properties, classification.

2. Digital memoryless modulation - linear/nonlinear (PSK, QAM, FSK, ?).

3. Digital modulation with memory - linear/nonlinear (TCM, CPFSK, CPM, ...).

4. Space-time, adaptive and multiplexing (ODFM) digital modulations.

5. Power spectrum density of digitally modulated signal.

6. Basic principles of channel coding.

7. Linear codes on GF. Block codes.
